2009-07-16cdc-eem: bad crc checkingVincent CUISSARD
When the driver received an EEM packet with CRC option enabled, driver must compute and check the CRC of the Ethernet data. Previous version computes CRC on Ethernet data plus the original CRC value. Skbuff is correctly trimed but the old length is used when CRC is computed. Signed-off-by: Vincent CUISSARD <vincent.cuissard@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-07-16E100: work around the driver using streaming DMA mapping for RX descriptors.Krzysztof Halasa
E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Unfortunately it fails to transfer skb->data ownership to the device after it reads the descriptor's status, breaking on non-coherent (e.g., ARM) platforms. This have to be converted to use coherent memory for the descriptors. Signed-off-by: Krzysztof Halasa <khc@pm.waw.pl> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2009-07-16bonding: clean muticast addresses when device changes typeMoni Shoua
Bonding device forbids slave device of different types under the same master. However, it is possible for a bonding master to change type during its lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND or the other way arround. The change of type requires device level multicast address cleanup because device level multicast addresses depend on the device type. The patch adds a call to dev_close() before the bonding master changes type and dev_open() just after that. In the example below I enslaved an IPoIB device (ib0) under bond0. Since each bonding master starts as device of type ARPHRD_ETHER by default, a change of type occurs when ib0 is enslaved. This is how /proc/net/dev_mcast looks like without the patch 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 01005e000116 5 bond0 1 0 01005e7ffffd 5 bond0 1 0 01005e000001 5 bond0 1 0 333300000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 333300000001 6 ib0 1 0 01005e000001 6 ib0 1 0 01005e7ffffd 6 ib0 1 0 01005e000116 6 ib0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff00000000000000000001 and this is how it looks like after the patch. 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 00ffffffff12601bffff00000000000000000001 5 bond0 1 0 00ffffffff12401bffff0000000000000ffffffd 5 bond0 1 0 00ffffffff12401bffff00000000000000000116 5 bond0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 00ffffffff12401bffff00000000000000000116 6 ib0 1 0 00ffffffff12401bffff0000000000000ffffffd 6 ib0 2 0 00ffffffff12401bffff00000000000000000001 6 ib0 2 0 00ffffffff12601bffff00000000000000000001 Signed-off-by: Moni Shoua <monis@voltaire.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

2009-07-09cxgb3: Fix crash caused by stashing wrong netdev_queueRoland Dreier
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

2009-07-09ixgbe: Fix coexistence of FCoE and Flow Director in 82599Yi Zou
Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR) in 82599 and remove the disabling of FDIR when FCoE is enabled. Currently, FDIR is turned off when FCoE is enabled under the assumption that FCoE is always enabled with DCB being turned on. However, FDIR does not have to be turned off all the time when FCoE is enabled since FCoE can be enabled without DCB being turned on, e.g., use link pause only. This patch makes sure that when DCB is turned on or off, FDIR is turned on or off correspondingly; and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

Atheros top level menu needs a "depends WLAN_80211" to properly indent within menuconfig and xconfig interfaces. This is purely a visual issue but it effects all subsequent drivers. The issue is the top level menu does not include a dependency on WLAN_80211 so within the tree structure, Atheros is at the same level as WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with all subsequent drives, so it is really a subordinate.

2009-07-08zd1211rw: 07b8:6001 is a ZD1211BPascal Terjan
On a shuttle machine here we got 07b8:6001 device, handled by zd1211rw, which does not work. Scanning is OK but association does not work, we get "direct probe to AP xxx timed out" It appears that this simple patch makes the device work perfectly. This id was already there in initial import of the driver so I don't know if it has ever been working as ZD1211 (which would mean they changed it and kept the id :( ).

2009-07-08r6040: restore MIER register correctly when IRQ line is sharedFlorian Fainelli
When the r6040 device IRQ line is shared we will enter the driver interrupt service routine, mask off the device interrupt enable register (MIER) and return with IRQ_NONE, we would then leave the device with interrupts disabled, this patch fixes that issue.

2009-07-08igb: set lan id prior to configuring phyAlexander Duyck
The igb driver was defaulting to using the lock for pci-e function 0 for all of the phys due to the fact that the lan id was not being set prior to initialization. This change makes it so that the function id is set prior to checking for the phy id.

2009-07-07ath9k: Fix leak in tx descriptorVasanthakumar Thiagarajan
When we reclaim the tx desc, we always assume that the last desc is a holding desc, which is not true, and skip it. If the tx queue is drained during channel change, internal reset and etc, the last descriptor may not be the holding descriptor and we fail to reclaim them. This results in the following two issues. 1. Tx stuck - We drop all the frames coming from upper layer due to shortage in tx desc. 2. Crash - If we fail to reclaim a tx descriptor, we miss to update the tx BA window with the seq number of the frame associated to that desc, which, at some point, result in the following crash due to an assert failure in ath_tx_addto_baw(). This patch fixes these two issues. kernel BUG at ../drivers/net/wireless/ath/ath9k/xmit.c:180!

MT26468 (PCI ID 0x6764) devices can expose multiple physical functions. The current driver only handles the primary physical function. For other functions, the QUERY_FW firmware command will fail with the CMD_STAT_MULTI_FUNC_REQ error code. Don't try to drive such devices, but print a message saying the driver is skipping those devices rather than just "QUERY_FW command failed."
